HORIZONTAL SUPPORT FOR CONDUCTORS- To all 1071/0777/ may concern: l

Beit known' that I, LOUIS STEINBERGEII, a citizen of the United States, and a resident ot' the city of N ew yYork/, borough of Brooklyn, in the county of Kings and State of New York-have invented a new and lm roved Horizontal Support for Conductors. o fhich the following is a full, clear, and exact description. l

My invention relates to supports lor conductors, such as cables, wires and the like.

Among the several objects sought by my improved device are the following: fl. To provide an increased expanse of insulating material upon a cross arm oranalogous member disposed horizontally, for the purpose of preventing leakage from the conduc tor to the arm; 1I. To increase the extent of surface of the insulator so as to reduce the amount ofsurface leakage; III. To prevent the formation of arcs, by lengthening the path through which the are might otherwise tend to occur; IV. To provide improved facilities for mounting the insulator and for taking it down; V. To insure'the retention ol dielectric properties in the insulator, should a part of the construction be broken;

o prevent undue chai'ing or wearing oi' that part of the insulator upon which the cable or other conductingr Inember rests; VII. To clamp the cable or analogous conducting member in a predetermined position relatively tothe insulator; VIII. To provide the insulator with means for tightening and slackening the ca'ble; IX. To secure the wearing plate firmly in position upon the insulator y appropriate 'anchpragcs; X. To provide for regulating the degree of clamping pressure upon the cable or analogous member incidental to holding the cable firmly in relation to the insulator; Xl. To prevent undue rigidity in the clamping mechanism used for controlling theltension of theeable; XII. To reduce the number or' poles usually required for a given distance and XIII. o provide a line insulator of novel construction, which is mounted directly .upon and is supported by the cross-arm, thus, obviating the necessity of employing a pin/or other auxiliary device for supporting` the insulator, and also providing the greatest possible strength in the the employment of4 a greatly increased length of span between poles with )erl'e'ct safety. '.XIV. To provide a practicality storm-prooi' line insulator having means vor securelysupporting' the cable Specification of Letters Patent. Application filed December 10,

in a manner so as to make each span an independent .mechanical unit. i

Reference i's had to the accompanying drawings representing one 'form of my invention, in which drawings like characters of reference indicate like parts throughout the views, and in which Figure 1 is a l'ront elevation ol the insulator, the wires and all movable parts being removed; Fig. 2 is a fragmentar)v side elevation of the construction shown. in Fig. l Fig, .3V is a v .I'tic.al longitudinal section through an insulator and support therclor, made `in accordance with my invention, thc section being taken along the line 3*--3 ot' Fig. LL; liig. 4- is a central cross section upon the linc l--l oll Fig. 3, showing thc 'manner in which the cable is mounted. and in which the tension of thc cable is controlled; Fig. 5 is a perspective ol' the wearing plato uscd upon the top oli thc insulator to prevent thc material oli the insulator from becoming chal'ed by the action ol' thc cable; Fig. (i is a perspective of one member of a two-pari: clamp used for gripping the cable or its equivalent.

The cross arm is shown at edge 4 thereof is rounded. As indicated in. Fig. 2 the dimension representing the width of the cross arm may be greater than thc thickness thereof. Mounted upon thc cross arm is a saddle 5 of metal.- the upper portion of the saine being rounded so as to lit thc'upper surface 4 of the cross arm. Molded rigidly upon the saddle 5is a body portion or insulating material Inade comparativcly thick, and provided internally with petticoats 8 and 9, as will be understood from Fig. 2. A 'number of disks l() are integral with 7, and are spaced apart, as indicated In. Fig. '1, there being two of these disks ad'acent to each end of the body por tion. Tlie ends of the body portion are sloped, or provided with steps v11 for the purpose of uiding rain and other forms oi" moisture otl' In two directions, without allowing it to run downwardly upon the cross arm. The middle surface of the body ortion 7 is provided With corrugations 7, t Ie latter serving the double purpose of causing moisture to flow in two directions at right angles to thel general plane occupied by the cross arm, and of diminishin the chances of a surface leak` age. The sadzdle 5 is held in position by metallic spikes 12, 13, which are driven into the cross arm. The 'spike 13 is here shown as 3, and the upper'.

i slaekeii the cable 35.

,'lliis bolt engages the buckle extendingI through a hole '13 in the saddle 5 for the purpose of insuring that no displaceiiient can take place 4'as between the saddle and cross ariii. A wearing plate 14 having a generally arched form, as indicated in Figs it, if and 5, is provided with uiider-ciipping edges 1 5 having comparatively thiekpor-` i n r tions lo, and also having apertures 1 i. 1` his wearing plate 14 is 'further provided'with llaiiges 18 integralv therewith, the lower edges 19 olY these (langes, and also the under-cupping edges 15 being embedded withinl the general body of insulating material. lower edges 19 ot the body 7 of'insulating material are llush with the lower edges of the disks 10, as will be understood Vfrom vFig.y 2. The body portion is provided with horizontally disposed sheds 20, 21v and 22 which are spaced apart lor the double purpose decreasing surface leakage, and o'l` vfacilitating the drainage of moisture. The shed 22 is a little shorter than the sheds 21), 21 which are ot the saine length. The body portioiiT is further provided with a supporting portion 23, upon which tlieweariiig plate 14 is mounted, and into which the edges 15 and 19 `are embedded, as above described. A link 24.- is provided with a threaded bolt extending therelroiii. and connected with this boltis a revoluble buckle 26. Pins 27 pass through the thick portions 16 oi the weariiig'plate 111, and serve as pivotslor'tlie link 24, and a clamp 28. There are two of these claiii'ps,

each made in halves, one oi thesehalves being' shown iii perspective iii Fig. 4Q The inember 28 is bent later-ally atlQ, and terminates iii an eye 3() having a hole 31 therethrough. Said member 2S is `l'urtlier provided with an enlarged portion 32,. having holes 33 therethrough, and bent into semi-cylindrical `form at 34. llach pair o'i` parts oi" the kind just described is clamped upon a cable 35, ,and held in position relatively thereto and to each other by bolts 36. One oi the coinplcte clanip's'just described, at the left ol" Fig. 2, iscoiiiieeied by a pivot 37 with a bolt 3S, iii such a manner as not to be readily turned iii the direction of the axis ol" the bolt 3S. 26. rihe bolts threaded oppositely so that the buckle 2G teiids to tighten or 'lhe corriigatioi'is 7 have. a double ollice. 'l`hey serve to break up the siii-tace ol' the insulator, thus retarding thecreep oi'" moisture, and they also serve as rests l'or additional cables such as 39. (Fig. 2%.) ll'v Afor any reason, the cable 35 should bccoiiie diseoiiiieetial lroiii its fastenings, it. may still rest between the eorrugatioiis 7 lt will be. noted that the upper ends of the disks 1t) taper grz'tdua ly iii thickness and wires 41), 41, maytherefore be inserted intermediate o'l these disks and may be wedged iiito position therebetween so as to be held Iii-oily. In this i Tay a telegraph or telephone 25 and 3S are rotation ol' the The i threewire system will be supported without. I detriment to the general properties ot the iiil siilator.

l My invention is used as follows: 'lhe parts ybeing constructed as above described, the

l 'Wi'l 0r even a so-ealled third wire oi' a cable 35 rests centrally within the l plate 14, being retained therein partially by its own weight. The clamps and turn-buckles are next placed in positionfand ythe bolts 36 are given the proper degree oi` tightness to hold the clainpsiirnily in relation to. the lcable. By this means any sawing action due to longitudinal movement of the cable in' the direction of' its length is unable to cause abrasionor ch'aiing et the insulating material, for the reason ythat all wear is taken up by the wearing plate 14. It the cable should break, the slack caused by the break cannot extend any farther than the two insulators located upon the opposite sides oi the break. Il', new, it be desired to adjust the cable, for instance, accordingto the view shown in Fig. 2, to pull the cable to the right for the purpose of taking up slack toward the lef t, this maybe done bv turning the vturn buckle 26 so as to pull the cable inthe direction indicated. i lf need be', the clamp at the-right of the Fig. 2 may remain tight, while this is done, iii which event a small portion of the cable iiiteriiiediate of tlieelainps will buckle slightly, thus transferring most oi the strain from the top oi the wearing plate 14 i wearing plate.

course, sustained ultimately by the insulator, need not in every instance be upon the saine identicalpart ofthe insulator, and may be, distributed to considerable advantage so as to increase the strength oi the insulator.
